Application filed. February 29, 1915- Seral No. 9,682.

To all whom it may concern Be it known that I, DENNIS F. Fox, a citizen o the United States of America, residing at Candor7 in the county of Montgomery and State of North Carolina, have invented certain new and useful Improvements in Fuel-Heating Devices for Explosive-Engines, ot' which the following is a specitioation, reference being had therein to the accompanying drawino,

This invention relates to a means for heating' air to be applied 0r injGCteCl DO 21 C211- bureter of an explosive engine, and has for its object the productionvot` a simple and efficient means whereby air may be taken into the carbureter from a point adjacent the exhaust, which exhaust is, while the engine is running, very hot.

Other objects and advantages of the present invention will appear throughout the following specifications and claim.

In the accompanying drawings.-T

Figure 1 is a side elevation of the exT plosive engine showing the heating device applied thereto.

Fig. 2 is a perspective view of the heating device.

Fig. 3 is a central longitudinal section therethrough.

Flg. 4 1s a transverse section through the heater showing the manner in which the` same may be attached to the exhaust manifold of the enoine, the exhaust manifold and portion of the explosive cylinder being shown in dotted lines.

Fig. 5 is an enlarged longitudinal section of Fig. 3 taken on line 5 5, looking in the direction of the arrow.

B v referringto the accompanying drawing it will be seen that 1 designates the ex plosive engine which is provided with the usual exhaust 2. nn air inlet pipe 3 is clamped in engagement with the exhaust pipe 2 by means ot' clamps or other securing means 4. and this pipe 3 is provided with an open end 5, and upon the lower face thereotl is also provided with a plurality of air inlet apertures 6. It should be understood that. this inlet pipe 3 is adapted to lie snugly against the exhaust manifold 2 as clearly illustrated in Figs. 1 and 4 so as to permit the air to be taken into the inlet pipe 8 as close as possible to the exterior of the pipe 2. It should be understood that the inlet pipe 3 is not intended to take in the exhaust from the engine, but is adapted to The inner end of the inlet pipe 3 is conp nested. to an elbow 7, which elbow in turn engages a shank 8, wlnch shank-pipe isshdably mounted within auxiliary pipo 9, the

'pipe Qbeing connected to a dependin elbow l0. This elbow 10 engages one ond, of the' telescoping pipe 11, and the opposite end of thel pipo ll engages the elbow 1.2- The telesooplls pipe ll is. provided with a fresh air inlet aperture 13. which aperture iS norinailv closed. by a Sleeve 141,; the Sleeve l is provided with a lug` 14a (Fioj. 2) and an operating link 14h is connected to said lug 1113. The sleeve 14 is provided with an aperture 15 which is adapted to register with the aperture 13 clearly shown in Fior. 5 to permit fresh air to be admitted into the pipe 11 and be discharged into the nozzle 16 when it is desired that fresh air ybe admitted into the carbureter 17. It should be understood that the aperture 13 is of the same size as the discharge aperture 18 et the nozzle 1G, so as to permit a uni-form jet ot' air to pass from the aperture 13 out through the aperture 18. rihis nozzle is carried by the outer end of the elbow 12.

It should be understood that the pipes 8 and 9 telescope within each other and iit snugly together so as to permit the pipes to be adjusted to the diiierent type ot' engines employed upon diiiferent' make automobiles. and it should be understood that the pipe 11 is especially adapted to permit the adjustment of the pipe to the different type o1 engines used upon the different make of automobiles, motor cars, and the like. It is, of course, obvious that some adjustable mechanism, must be employed for the present device is adapted to be sold independently of the engine and is adapted to be applied to any make or design of an engine used upon motor cars without departing .from the spirit of the invention. 1t should be understood that the device may be made ot any size and any material, and other detail mechanical changes may be employed so long as the changes fall used uponv Vdifferent species 'of engines, and io" Within the scope of the claims Without departing yit'ronithe spirit of the invention. It

present device is especially adapted v'to be that Yowing to the adjustable feature there- Vvof the same may'bereadilyapplied to the exhaust pipe of an engine and connected to 'vthercarbureter for conveniently feeding hot "is claimed .as new, is Y In, an lapparatus of the class described,

or warm air to the carbureten'and it should be understood that when so desired, fresh air may be admitted to the carbureter by merely permitting the passage' of air vthrough the `aperture 13 by bringing the aperturesy 13 and 15 into such a Vposition'asy to ,permit the same toregister. VThe air', of

^ l coursefwill be drawn Vthrough the nearest point of Acommunication with the outside'Y atmosphere. t

Having thus described the combination of an inletY pipe provided -witha plurality of alined apertures formedv in one side thereof1 said .inlet pipe provided the invention what inserted into one end of'saifl elbow, an auxiliary pipe carried VbyfsaidV reducedY shanle' pipe, saidV auxiliary-,pipe provided with vertically'positioned elbow, Vsaid elbow provided with a two-section'telescoping pipe,

the lower'sectionof .said telescoping pipe being providednwith an aperture and with an elbow,the apertur'ed section of the telef 'scoping pipe being slidably mounted within lthe upper portion of said lelescoping pipe, Y a sleeve rotatablv mounted Vupon the lower,

section of the tei'eseoping pipe ybetween'the elbow and the upper section'of'said pipe,` said sleeve provided Awith lan aperture adapt-A ed to registerfwith thejapertureinV the lowerV section of the telescoping pipe, said sleeve provided with a horizontal lug, an operat# VingA link pivotally mounted in said lug,"and fa reduced nozzle carried bysaid last-mentioned elbow.A "f Y' In testiinonyrwhereo I hereunto myA signature in y,presence of tivo witnesses.
